"The electronic edition of Principles and Standards for School Mathematics. Principles and Standards extends the vision of NCTM's previous three Standards documents and represents a continuing effort to support mathematics teachers and ensure that every student receives a high-quality mathematics education. The document delineates six Principles that set forth important characteristics of Mathematics programs and ten Standards that discuss the mathematics students need to be able to know and do across the grades. The E-Standards includes all of the text of Principles and Standards, plus these added features: 'E-examples,' interactive applets and short videos that provide further insights into the messages of the document. Links to other resources, including the Illuminations Web site and NCTM's previous three Standards documents search capabilities and enhanced navigation."
